Abstract of the Disclosure The invention relates to an electric/secondary fuel furnace which includes a combustion chamber. The combustion chamber is tubular in shape and has an oval shaped cross-section and receives and burns wood fuel in one embodiment and gas or oil in the embodiment shown in the Supplementary Disclosure hereto. The combustion chamber is made of a heat exchange material. Heating elements are disposed externally of the combustion chamber on either side thereof. The combustion chamber is enclosed in a combustion chamber enclosure means which houses both the combustion chamber and the electrical elements and which also defines airflow paths on either side of the combustion chamber between the combustion chamber side walls and res- pective ones of the enclosure side walls. The combustion chamber enclosure includes a warmed air escape opening disposed over the combustion chamber. A fan enclosure means, which houses a fan, is disposed beneath the combus- tion chamber enclosure means, and there are provided means for providing air communications between the fan enclosure means and the combustion chamber enclosure means. Thus, air is forced from the fan enclosure along the air paths and out the air escape opening, the air being heated during its travel along the air paths.
